Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a seismic support node suitable for bolted ball grid structures. Background Technology

[0002] In the field of modern architectural engineering, with the rapid development of the social economy and the ever-increasing demand for public activity spaces, various large-scale public buildings have sprung up like mushrooms after rain. In my country, the design and selection of the roof structure is crucial for many public buildings with large spans, such as stadiums, gymnasiums, theaters, and large coal yards. Considering factors such as structural stability, ease of construction, and cost-effectiveness, bolted ball steel space frames, with their unique advantages, are widely used as the main roof structure. Bolted ball steel space frame structures are composed of bolted balls, rods, and other components connected by bolts. They feature good spatial load-bearing performance, aesthetic appeal, and convenient installation, effectively meeting the spatial requirements of large-span buildings. However, in practical applications, especially under certain special geographical conditions, this structure has revealed certain limitations.

[0003] In earthquake-prone areas, the intense seismic forces generated by earthquakes can cause tremendous impact and vibration on building structures. Traditional bolted ball joint supports, due to their structural features and connection methods, are insufficient in resisting seismic forces. When an earthquake occurs, these supports struggle to effectively transmit and disperse seismic forces, easily leading to localized damage or even complete collapse of the structure, seriously threatening the safety of buildings and the lives and property of people.

[0004] In areas heavily affected by typhoons, the powerful horizontal wind loads brought by typhoons also pose a severe challenge to bolted ball steel space frame structures. Traditional bolted ball space frame supports have limited wind resistance when subjected to horizontal wind loads and cannot fully withstand the impact of typhoons. This may lead to problems such as deformation of the space frame structure, loosening of members, or even detachment, affecting the normal use and service life of the building.

[0005] The above shortcomings need to be improved. Utility Model Content

The first hanging ears are provided with first elongated limiting holes that are transverse and allow the roller shafts to pass through.

[0023] The fixing part includes a mounting base and a pair of second hooks disposed on the top of the mounting base. The second hooks are provided with a second elongated limiting hole that is transverse and allows the roller shaft to pass through.

[0024] The motion roller abuts between the mounting top and the mounting base and is capable of rolling in the horizontal direction to create a displacement difference between the mounting top and the mounting base in the horizontal direction.

[0025] In a preferred embodiment of this utility model, the bolt ball is welded to the top of the bolt ball support.

[0026] As a preferred embodiment of this utility model, the bolt ball is made of 45# medium carbon steel.

This helps to reduce energy loss and structural deformation during load transfer, and enables horizontal and vertical forces to be effectively transferred through various components. This ensures the smoothness and stability of force transmission in the entire bolt ball space frame structure, and further improves the safety and reliability of the structure.

[0037] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. It is also declared that the embodiments described below are only for explaining this utility model and are not intended to limit this utility model.

[0039] Please see Figure 1 , Figure 2 This embodiment provides a seismic support node suitable for bolted ball space frames, including multiple space frame rod assemblies 1, bolted balls 2, bolted ball supports 3, force transmission supports 4, and rolling seats 5. The multiple space frame rod assemblies 1 are circumferentially detachably connected to the upper surface of the bolted balls 2. The bolted ball supports 3 are disposed at the bottom of the bolted balls 2. The force transmission supports 4 are detachably connected to the bottom of the bolted ball supports 3. The rolling seats 5 are disposed at the bottom of the force transmission supports 4, and the force transmission supports 4 are connected to the roof structure via the rolling seats 5. The rolling seats 5 include a rolling part 51 and a fixed part 52 disposed below the rolling part 51. The rolling part 51 can move horizontally relative to the fixed part 52. By setting a rolling seat 5 at the bottom of the support, the horizontal displacement of the bolted ball space frame and the support can be released. When encountering horizontal loads such as earthquakes or typhoons, the rolling part 51 of the rolling seat 5 can move horizontally relative to the fixed part 52, so that the bolted ball space frame can move to a certain extent with the direction of the horizontal force, allowing the structure to better adapt to the horizontal force and avoid structural damage due to limited horizontal displacement. This greatly improves the ability of the bolted ball space frame to withstand horizontal wind loads and resist earthquakes, ensuring production safety and the safety of life and property of personnel in earthquake-prone areas and areas heavily affected by typhoons.

[0040] Because the force transmission support 4 and the bolt ball bearing 3 are detachably connected, the upper and lower parts of the seismic bearing node can be installed separately. In actual installation, the lower force transmission support 4 and rolling bearing 5 are first installed on the roof structure. Then, the upper multiple space frame rod components 1, bolt ball bearing 2, and bolt ball bearing 3 are assembled, and finally, the upper part is installed on top of the lower part. This step-by-step installation method reduces the difficulty and complexity of installation. Compared to overall installation, separate installation is easier for construction personnel to operate, improves installation efficiency, and also facilitates adjustments and calibrations during installation, ensuring the accuracy and reliability of the installation.

[0041] The connection methods between the various components of the above-mentioned seismic support nodes are reasonable. From the circumferential detachable connection of multiple space frame rod components 1 to the upper surface of the bolt ball 2, to the connection between the bolt ball support 3 and the bolt ball 2, and between the force transmission support 4 and the bolt ball support 3, the reliability of the structural connection is guaranteed. The reliable connection method helps to reduce energy loss and structural deformation during load transfer, so that horizontal and vertical forces can be effectively transferred through each component, ensuring the smoothness and stability of the force transmission of the entire bolt ball space frame structure, and further improving the safety and reliability of the structure.

[0042] Please see Figure 2 In one embodiment, the space frame pole assembly 1 includes a space frame pole 11, a conical sleeve 12, a nut sleeve 13, a first high-strength bolt 14, and a pin (not shown in the figure, the same below). The tail of the conical sleeve 12 is connected to the end of the space frame pole 11. The head of the first high-strength bolt 14 is located inside the conical sleeve 12, and the thread of the first high-strength bolt 14 extends outward along the end of the conical sleeve 12. The nut sleeve 13 is threaded onto the thread of the first high-strength bolt 14 and locked to the thread of the first high-strength bolt 14 by the pin. The upper surface of the bolt ball 2 has a plurality of first bolt holes 21 circumferentially formed to mate with the first high-strength bolt 14. The pin allows the nut sleeve 13 and the first high-strength bolt 14 to rotate synchronously, thereby facilitating the user to lock the first high-strength bolt 14 into the first bolt holes 21 of the bolt ball 2 through the nut sleeve 13. This enables the quick installation and disassembly of the space frame pole 11 and the bolt ball 2, improving construction efficiency and facilitating subsequent maintenance and repair.

[0043] In one embodiment, the nut sleeve 13 has a pin hole (not shown in the figure, the same below) that mates with the pin, and the first high-strength bolt 14 has a pin groove (not shown in the figure, the same below) that mates with the pin. The pin hole and pin groove ensure that the pin can effectively connect the nut sleeve 13 and the first high-strength bolt 14 together, ensuring that the two can rotate synchronously, further enhancing the stability and reliability of the connection.

[0044] In one embodiment, the tail of the cone sleeve 12 is welded to the end of the space frame member 11. The welding connection method can provide high connection strength, ensuring a firm connection between the cone sleeve 12 and the space frame member 11, so that the entire space frame member assembly 1 can work stably when bearing loads and is not prone to loosening or falling off.

[0045] Please see Figure 1 , Figure 2 In one embodiment, the top of the force-transmitting support 4 is connected to the bottom of the bolted ball support 3 via a second high-strength bolt 6. This bolted connection effectively transfers loads, ensuring a reliable connection between the upper and lower parts of the seismic support node. The high-strength bolts possess high strength and preload, maintaining connection stability under heavy loads and ensuring structural safety during operation.

[0046] Specifically, the bottom of the bolted ball bearing 3 is provided with a first flange 31, on which multiple second bolt holes 311 are formed to mate with the second high-strength bolts 6; the top of the force transmission bearing 4 is provided with a second flange 41, on which multiple third bolt holes 411 are formed to mate with the second high-strength bolts 6. The arrangement of the first flange 31 and the second flange 41 increases the connection area between the bearings, allowing for a more even distribution of load and further improving the reliability and stability of the connection. At the same time, this structure facilitates installation and disassembly; during construction, the force transmission bearing 4 and the bolted ball bearing 3 can be quickly connected together using bolts, improving construction efficiency.

[0047] In one embodiment, the rolling part 51 is welded to the bottom of the force transmission support 4. This welding connection ensures a firm connection between the rolling part 51 and the force transmission support 4, enabling the rolling support 5 to function stably during operation. As a key component for releasing horizontal displacement, the firm connection between the rolling part 51 and the force transmission support 4 is an important prerequisite for ensuring that the entire seismic support node can effectively adapt to horizontal forces, thereby further improving the wind and seismic resistance of the bolted ball grid structure.

[0048] Please see Figure 3In one embodiment, the rolling part 51 includes a motion roller 511, a mounting top seat 512, and a pair of first lugs 513 disposed at the bottom of the mounting top seat 512. The motion roller 511 has roller shafts 5111 respectively passing through the pair of first lugs 513 on both sides. The first lugs 513 have first elongated limiting holes 5131 that are transverse and allow the roller shafts 5111 to pass through. The fixing part 52 includes a mounting base 521 and a pair of second lugs 522 disposed at the top of the mounting base 521. The second lugs 522 have second elongated limiting holes 5221 that are transverse and allow the roller shafts 5111 to pass through. The motion roller 511 abuts against the mounting top seat 512 and the mounting base 521 and can roll in the horizontal direction to form a displacement difference between the mounting top seat 512 and the mounting base 521 in the horizontal direction. When a horizontal load (such as the horizontal force generated by an earthquake or typhoon) is applied, the rolling of the motion roller 511 can create a displacement difference in the horizontal direction between the mounting top seat 512 and the mounting base 521, thereby realizing the release of horizontal displacement of the bolted ball grid frame and the support. This can effectively buffer and disperse the horizontal force, avoid excessive stress in the structure due to the limitation of horizontal displacement, and improve the wind and earthquake resistance of the bolted ball grid frame structure.

[0049] In one embodiment, the bolt ball 2 is welded to the top of the bolt ball bearing 3. Through welding, the bolt ball 2 and the bolt ball bearing 3 form a single unit, ensuring that during load transfer, force can be effectively transferred from the bolt ball 2 to the bolt ball bearing 3, and then to the roof structure via subsequent force-transfer bearings 4 and other components. This connection method guarantees the stability of the structure under various loads (including horizontal and vertical forces), reduces the risk of structural failure due to loose connections, and improves the reliability and safety of seismic bearing joints.

[0050] In one embodiment, the bolt ball 2 is made of 45# medium carbon steel. 45# medium carbon steel possesses high strength and excellent comprehensive mechanical properties, such as high yield strength and tensile strength. Using 45# medium carbon steel to make the bolt ball 2 ensures that it is less prone to deformation or damage when bearing various loads transmitted from the space frame members 11, thus guaranteeing the load-bearing capacity of the bolt ball 2. Simultaneously, its excellent comprehensive performance also helps improve the stability and reliability of the entire bolt ball space frame structure, enabling it to function better in complex working environments (such as earthquake-prone areas and regions heavily affected by typhoons), ensuring the safety of the building.

[0051] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
